MIGHAEIJ HURLEY, OF CHICAGO, ILLINOIS.

WINDOW-CLEANER.

SPECIFICATION forming part of Letters Patent No.2'74,334, dated March 20, 1883.

Application filed August '1, 1882. (No model.)

To all whom it may concern Be it known that I, MICHAEL HURLEY, a citizen of the United States of America, residing at Chicago, in the county of (look and State of Illinois, have invented an Improve ment in Window-Cleaners, of which the following is a specification.

My invention relates to an improvement inscaifolds for cleaning windows, andother like uses; and it consists in a scaffold provided with a railing, and adapted to clamp the window-frame upon both inside and outside, as will be more fully explained hereinafter.

To enable others to avail themselves of the benefits of my invention, I will now proceed to describe its construction and operation, referring to the accompanying drawings, in which- Figure 1 is a perspective view of my invenlion 5 Fig. 2, a vertical longitudinal section of the same, and Fig. 3 a detail view of a modification of a part thereof.

Similar letters refer to similar parts th roughout the several views.

A represents the baseboard, of suitable length, and widened out on its outer end to form a platform, A, which is provided with a railing, B, to prevent accidents when the device is being used.

O is a cross-bar of sufficient length to extend across any window and bear against the molding upon each side. This bar is secured to the base-board by a bolt, 0, passing down through a longitudinal slot, at, in said board, and having a nut on the under side. The ends of "the cross-bar are covered with rubber, as seen in Fig. 1, to prevent injuring the molding or scratching paint when in use. On the inner end of the base-board Ais a strip of metal, D, extending both above and below the board, and having a hole through each end to form a bearing for a screw-rod, E, which rod has its outer end bent to form a crank-handle, and its inner end passing through an adjustable bearing, F, and abutting against the cross-bar O. The bearing F is formed with a screw-threaded hole through its head or upper end, and pro vided with a shank passing down through the slot a, and a nut upon its lower end to secure it in any desired position in the slot.

0! is a second cross-bar,similar to the other, and secured by a long bolt, 0', passing through one of a series of holes in the base-board, each hole being provided with a thread-nut, I), let into the boardA flush with its under surface, as seen in Fig 2. The bolt 0 is provided with a set-nut above the cross-bar, and its lower end is extended downward to form a bearing on-the window sill. The under side of the base-board A is provided with a cushion, a, to prevent injury to window-sills on which it may rest. may, if desired, be providedwith a curtain,

d, which is secured by buttons d, similar to a.

' in position and adjusted forward in the slot until it bears against the window-frame. The screw-rod E is now turned up against the bar 0 and forces it firmly against the frame, where it is held by the nut on the lower end, of the bolt 0, the rubbers on the ends of the bar socuring the molding from injury. In cases where inside shutters are used they must be folded back, and to prevent any injury to them I remove the rubbers from the cross-bar G and replace them with the block f, (shown in Fig. 3,) which is grooved on its outer edges to fit the molding and holds the bar away from the shutters. The window-frame being new tightly clamped by the two cross-bars, and the baseboard resting on the cushion c and long bolt 0, the device is ready for use, and is perfectly safe, very convenient, and cheap of construction. In some cases it may be found convenient to place the bar 0 upon the under side of the base board, in. which case the screw-rod E is withdrawn and inserted in the other end of the bearing D. The bearing F is loosened and withdrawn,without removing the nut, through the enlargement a of the slot at, and inserted again from the under side, and the operation is performed exactly as before. It is obvious The railing around theplatform] I may bindthe edges of the slot, edge of the platform, the cross-bars, and all exposed surfaces with metal to protect them.

Having thus fully described my invention,

IOO

what I claim as new, and desire to secure by Letters Patent, is- A 1. The combination, in a window-scaffold, of the adjustable clamping-bars G O, with bolts 0 c, slotted. base-board A, and screw-rod E, with its beariu gs D F, all constructed and an ranged to operate substantially as and for the purpose set forth.

2. The combination, with the base-board A, provided with curtained railing B and slot a, of the two rubber-tipped adjustable cross-bars 0 0, bolts and nuts 0 c, screw-rod E, with its bearings D F, and the cushion a, all constructed andarranged as and for the purpose herein specified.

In testimony whereof I affix my signature in presence of two witnesses.

MICHAEL HURLEY.'
